基于设计速度的详细规划层面道路横断面研究

On the Roadway Cross-Section Design Based on Design Speed at Detailed Planning Level

从详细规划重要参数指标——道路红线与道路设计核心参数——设计速度出发,建立设计速度与道路红线宽度、横断面布置之间的联系,利用城市规模、道路等级和道路功能等重要因素,提出不同规模城市,各级道路可选择的红线宽度和断面布置,为详细规划提供科学规范的建议和参考。

This paper studies on important parameters from the detailed planning-road red line,the core parameters from road design-design speed,and the connection between the design speed and road red line width,cross-section layout.By using of urban population scale,road grade,road function and other important factors,puts forward that different scale cities can choose the red line width of road and cross-section layout.Scientific and standardized advice and reference for detailed planning are also provided.
